Dallas Cowboys Football Stadium, Arlington/Texas, USA, 2009

It is the most spectacular stadium in the world, an architecturally-significant and technologically advanced sports venue. The 3 million-square-foot stadium has an approximate capacity of up to 100,000 fans. As the largest NFL venue ever built, the new stadium boasts the most spectacular column-free room in the world, stretching a quarter-mile in length. The stadium features two monumental arches, soaring 292 feet above the playing field, which support a retractable roof. Designed to be open or closed, depending on weather conditions, the expansive retractable roof is the largest of its kind in the world and measures approximately 660,800 square feet. When closed, the roof encompasses 104 million cubic feet of volume, making it the largest enclosed NFL stadium in the world. Each panel can open or close in 12 minutes.

One of the most compelling architectural features of the stadium design is the canted glass exterior wall. The 86-foot-high glass, curtain-wall surface slopes outwardly at a 14-degree angle to create a luminescent glow, day or night. A fritted glass system transitions up the elevation to create a dynamic, ever-changing aesthetic depending on the time of day. At night, a series of internal lights gently wash the glass wall to create a glow across the façade.Within the seating bowl, Cowboys fans will be provided with a one-of-a-kind feature, a centerhung video board. Hanging approximately 90 feet above the field from the roof structure, the innovative video center spans between the 20-yard lines and features four individual boards – two facing the sidelines and two facing the end zones. The sideline boards measure 72 feet tall by 160 feet wide – big as two basketball courts - , while those facing the end zones measure 27 feet tall by 48 feet wide. All four boards are angled toward the stands for optimal viewing. Weighing almost 1.2 million pounds, this is the largest video board in the world.
